Title: Stepper motor and driving control method therefor
Inventor: YAMAMURA YOSHIYA
IPC: H02P8/00
Filed: 2001-05-25
Abstract: PROBLEM TO BE SOLVED: To provide driving control method for stepper motor wherein step out is prevented, exciting currents are made appropriate, the movement of step rotation is matched with a command value even in such a state that instantaneous stop is caused by overload, a stator is excited with efficiency, and a stepper motor is driven with stability even in high-speed ranges. SOLUTION: The phase between a sensor signal S for rotor position and a phase switching signal P for stator excitation is monitored, and an exciting signal V is generated based on a signal in lagging phase to control phase switching. An exciting current is so controlled that the exciting current is reduced when the sensor signal S is in leading phase and is increased when the sensor signal S is in lagging phase. The phase switching signal P and the sensor signal S are counted, and further the difference between the counts of both the signals is monitored. When both the signals are displaced by one pulse or more, phase switching control and exciting current control are exercised for acceleration if the phase switching signal is higher, and phase switching control and exciting current control are exercised for deceleration if the sensor signal is higher.  This control on acceleration/deceleration driving is exercised until the difference between the counts converges to zero.
